We Keep Your Diesel Running Strong

We Offer Diesel Service When You Need It

Diesel engines are known for their power, durability, and efficiency, making them popular for trucks, commercial vehicles, and heavy-duty applications. Unlike gasoline engines, diesel engines use compression to ignite fuel. They also rely on different parts, such as diesel particulate filters and glow plugs. These powerhouses are built to handle tough conditions and heavy loads. But when something goes wrong, it takes the right expertise to fix it properly. At Peterson Automotive and Diesel in Washington, Illinois, we’re your local diesel repair specialists with the training and experience to diagnose and fix any diesel issue that comes our way. We use advanced tools, follow manufacturer guidelines, and work on all makes and models. Whether you drive a Dodge Cummins, Ford PowerStroke, Chevy Duramax, or another type, you can count on us for expert-level service that keeps your engine in top condition and running strong.    

Types of Diesel Problems   

Diesel engines are tough, but they’re not immune to problems. Common symptoms of diesel issues include hard starts, excessive smoke, loss of power, rough idling, and unusual knocking noises. These signs can point to underlying problems, from clogged EGR valves and malfunctioning glow plugs to fuel contamination and carbon build-up. The longer they go unaddressed, the more extensive and expensive the proper diesel repair can become. That’s why bringing your vehicle to a shop that knows diesels inside and out is important. Our diesel repair technicians are experts in diesel diagnostics and repair, approaching every job with precision and care. We don’t just guess at the issue — we use cutting-edge equipment and methodical processes to pinpoint the exact problem. Once diagnosed, we’ll walk you through your diesel repair options and get the job done right the first time. You can trust us to restore your diesel’s performance and reliability.
